1. Introduction 1-1. Purpose of Xpress “Xpress” is a selection software for VRV and CMSQ systems. “Xpress” helps your quick selection for quotation with easy operation. V6.0.0 Uses the New Selection Procedure (NSP): indoor capacity is kept and all losses are recalculated to the outdoor units capacity.

1-2. Limitations on Selection “Xpress” has some limitations on selection. 1)

The capacity correction factors corresponding to height difference between outdoor unit and indoor unit are simplified. They are used depending on the relative position of the outdoor units such as “Higher”, “Same level”, or “Lower”.

2)

Though you can input the exact height of the outdoor units, the value is used only for checking the limitation of the height difference.

3)

Capacities are not completely equal to Engineering Databook. The Xpress uses an approximation formula made from the capacity table to calculate capacity. Differences should be less than 1%.

4)

Design temperature can be inputted outside the scope of the capacity table range. Data input only has a range check. The actual check of the temperature to be within the capacity table range is done during the selection. Values outside this capacity table range result in an error message on the outdoor unit.

5)

The sensible capacity is calculated from the actual total capacity, the by factor and the fan airflow at high speed. Therefore, this calculated capacity may differ slightly from the sensible capacity value of the databook.

6)

The order of indoor units is determined by the piping layout. Therefore, the wiring diagram does not always correspond to the field (actual) diagram. However, they can be set equal by moving indoor units up and down in the tree view.

7)

The order of outdoor units does not affect piping and wiring diagrams. If you change the order of outdoor units, the order will be changed on the report file.

8)

Some options are not displayed on the [Piping] tab and the [Wiring] tab.

9)

We strongly advise to use the function “Enter individual piping lengths manually” instead of relying on the automated piping length calculation by filling out the “Equivalent piping length” and “First branch to indoor units”. The automated calculation may result in a rough estimation. Therefore, the correction of the capacity towards the outdoor unit and the size up of the piping diameters may not be accurate. Also, in this case there is no calculation of the additional refrigerant charge.

5

1-3. Live update The VRV Xpress software is equipped with a Live Update feature. Thanks to this feature, the end can decide any time to check if a new version of the software is available, and if so, to and install it. Live Update Procedure: From within the software, through the welcome screen (first screen you see when starting the program), or through the about... menu, you can check for more recent versions that are available: Availability: Live Update is available on all software programs that are available on the Mantra II server. Note that a major update e.g. V5 to V6 is not within the live update scheme and requires a new install of the program. If you are still using an older version of the software, we recommend to and install the latest version. Never rename the executable file name of the program, otherwise the “Live-Update” function will NOT work !

The drop-down list varies depending on the models the software includes. 3) Select the outdoor unit family (type) from the drop-down list. The family (heat pump, heat recovery or cooling only) depends on the models the software includes. 4) Select the combination ratio between indoor units and outdoor unit from the drop-down list. Xpress selects the outdoor unit so that the combination ratio is equal or less than the selected value. 5) Input the outdoor design temperature (dry bulb) for cooling and heating. The temperatures should be chosen inside the scope of the capacity table. 6) Choose how to define the piping length: If you want to calculate the additional refrigerant to be charged and a thorough check on the pipe rules, click the [Enter individual piping length manually] check box, and then you can input the individual piping lengths manually on the [Piping] tab. (See section 7-2-2)

32

If you don’t want to calculate the additional refrigerant to be charged, uncheck the box and input the equivalent piping length and the piping length from first branch to indoor units. The pressure drop due to bends and Refnets have to be included in this total. *Equivalent piping length: the piping length between outdoor unit and the farthest indoor unit. It is used to correct capacities of the indoor units. *First branch to indoor units: the piping length between first branch to the farthest indoor unit 7) Select the position of the outdoor units relative to the indoor units. When choosing “Higher” or “Lower”, you can enter the difference in height manually.

8) Click [Select Options] to select options for the outdoor units. (See section 6-5 for details) 9)  indoor total capacity (heating and cooling): Here the operational load percentage is default set to 100. This is the sum of the capacities of all the indoor units in the system. When you know that not all these units would be in simultaneous operation, you could decide to downsize the installed systems capacity by the selected percentage. Needles to say that this is a delicate decision. That is why the next message pops-up: In the software, the operational load can be defined in 3 ways 1) As a percentage of the total load (for both cooling and heating) 2) As an absolute value (kW) (for both cooling and heating) 3) By selecting the indoors units that operate simultaneously. In this case, make the selection for the most dominant mode (cooling or heating) (3)

(1): tick “operational load selection (2): Right-Click an indoor unit and choose NOT to use for operational load calculation (3): grayed-out zones; read only.

6-4. Connect Indoor Units to Outdoor Units 6-4-1. Heat Pump and Cooling Only 1) Drag indoor units from the [Available indoor units] window to the outdoor unit of your choice in the [Outdoor unit] window. (1)

To disconnect an indoor unit with an outdoor unit; drag the indoor unit from the [Outdoor unit] window back to the [Available indoor units] window. Repeat the procedure (1) until you have connected all relevant indoor units to the outdoor unit.

Note: Xpress uses REFNET ts for piping by default. If you want to use REFNET headers, go to procedure (2), otherwise go to procedure (3). 2) Choose connections of header from drop-down list, then click the header button ( ) to insert a header. Now connect indoor units to the header as described in procedure (1).

Note: Each REFNET header has a limited number of connections. If you try to connect more indoors units than there are connections, an error window will pop-up.

6-4-2. Heat Recovery 6-4-2.1 BS-box Indoor units cannot be connected to heat recovery model outdoor units directly (except for cooling only mode). For heat recovery operation, a BS-box is necessary. The [Add BS] button ( ) becomes available when “Heat Recovery” family is selected. Click the [Add BS] button to add a BSBox to the outdoor unit. Next, connect indoor units to the BSbox as described in section 6-4-1.

Note: When indoor units are connected directly to the outdoor unit, they can only operate in cooling only mode. In this case, the caution icon ( ) will be displayed at the left side of the indoor unit icons and a caution message will be displayed at the bottom of the window.

36

6-4-2.2 Hydrobox You can also add a Hydrobox directly to the heatrecovery outdoor unit (no BS-box in between).

Note: You can only add a hydrobox when you select [Heat recovery] family and [VRV III REYAQ] series.

6-8. Change the Order of Outdoor Units To change the order of outdoor units, drag and drop outdoor units in the system list window. If you drag the outdoor unit onto another unit, it will be inserted before the other unit. To insert the [Out Hall1] before [Out Room2], drop [Out Hall1] onto [Out Room2].

To move to the last position, it takes 2 steps. First move the outdoor unit that you want to move to the last position onto the last outdoor unit. Then move up the last outdoor unit. Note: This change is only applied in the [Outdoor Units] tab page. The outdoor units order in other tab pages don‟t change unless you delete one.

6-9. Change the Order of Indoor Units The order of indoor units is very important for the piping layout. Define the order in consideration of the actual indoor units grouping and piping layout. To define the order, recommended basic rules are: - Create indoor units groups (e.g. units for each room) - Change the order of groups based on the distance from the outdoor unit (from the farthest group to the nearest group) - Organize the indoor units in the group, by number (name)

39

In the case of the next figure, recommended order is : 3-1

3-2

2-1

To change the order of the indoor units, drag and drop indoor units in the system list window. To insert Unit 1 before Unit 2, drop Unit 1 onto Unit 2. To move to the last position, drop the indoor unit onto the outdoor unit. Changing the order of indoor units will affect the [piping] and [wiring] diagrams.

Note: Changing the order in the [Outdoor Units] tab page has no relation with the order of indoor units on the [Indoor Units] tab page. The order should be defined according to actual layout.

7-4. Printing large piping diagrams When the piping diagram is printed in the report, it is always printed “shrink to fit page”. For VRV systems with many indoor units, this results in a report where the names of the units are no longer readable. Therefore, it is possible to cut the diagram into several parts and label each part. Each part is then printed on another page in the report, with its label in the sub diagram title. The cuts need to be defined in the [Piping] tab. You can define a cut by clicking on the intermediate pipe part where you want to cut the diagram. Then right click and select “Enter Subdiagram label”. The screen “Enter Subdiagram Label” appears, which allows to enter a label for the subdiagram. Suppose we enter “A”.

After entering the label, click “OK”. The label “A” appears on the intermediate pipe that will be cut.

Enter the other cuts in the same way. It is advisable to create the .rtf-output to see the result. If you are satisfied with the result, save your project. The labels are stored within the project.

54

In order to print the complete piping diagram again in the report, all the labels need to be removed. To remove a label, click on the intermediate pipe that is labeled. Right click and select “Enter Subdiagram Label”. The “Enter Subdiagram Label” screen appears, with the label you have entered. Delete the label and click “OK”. The label is now removed. Repeat this procedure for each label that was defined. Afterwards, save your project to remove the labels permanently.

9. Centralized Controller 9-1. F1/F2 circuit limitations •max 128 indoors •maximum 64 addressed indoors •maximum 10 outdoor systems (an outdoor system can consist out of several modules )  So it is possible to have 35 addressed and 93 unaddressed indoor units on one F1/F2 circuit Important Remarks: •In case the selects PPD option (available on iTouch, iManager or BACnet) then the max. indoor limitation is 64 (all indoors need to be addressed) •LON Gateway SNVT limitation, see 9-9 •EKEXV and Hydrobox cannot be connected to F1/F2 •In case the selects ACNSS (Airnet) option, then max. indoor limitation is 127 (address 2 till 128)  is not considered in the software!!

9-2. Allowed combinations

(*) iTC and LON can only be used in address range 1-00 ~4-15 (**) iManager, Bacnet GW and LON are always master

9-4. This example: We added several systems with a varying number of indoor units. The whole site will be managed by an Intelligent Manager, whilst some part of the building is controlled by one Intelligent Controller and the other part of the building/site by another ITC in a so-called “Control Group”…

9-5. Step 1

Drag the outdoor units (one by one) to the „Control Groups‟ zone

The total number of outdoor units (8) and indoor units (170) in the control group is indicated

9-6. Step 2

Drag the controller

60

Drag and drop the controller to the „specific controller‟ zone. Note that two ITC will be required.

Possibly, also a global controller is required…?

9-7. The Wiring-tab Access to wiring by clicking

or

Number of indoor units connected to one outdoor unit

To control the 170 indoor units two ITC and one DIII Net Plus Adaptor Will be required.

Notice that the logic numbering of the outdoor units is changed… The program will look for the best / most economical way to connect a maximum of 64 indoor units to one Intelligent Touch Controller. In this example, the outdoor units 2, 5, 3, 7 and 4 are connected to the first ITC. Outdoor unit 2 has 34 indoor units; outdoor unit 5 has 30 indoor units. This thus totals 64, the maximum for one ITC. The DIII-adaptor will take care of the indoors connected to outdoors 3, 7 and 4

The second Intelligent Touch Controller will take care of the indoors that are connected through the F1/F2 wiring to outdoor units 6 (16 indoors) and 8 (7 indoors) Possibly, the whole site is also managed by one Intelligent manager. (global controller)

61

The selection software will thus automatically Add units to a centralized controller. To do so, it is very likely that the combinations will not correspond to the physical location of the outdoor units. Consequently the “F1/F2 OUT” cabling will need to be routed according the sequence decided by the program. This is not always possible or is not always convenient… Thereto, a split can be made

62

9-8. Add a split in the central control

1) Select the unit above which you want to add the split in the system

2) Click on “Add Split”

Using this possibility, we refuse the optimum result proposed by the software… This results into the need for two ITC but furthermore also two DIII adaptors !

You can move a unit to “above the split” or to “below the Split” by selecting the unit and then use the arrow buttons.

To remove the split: Select the split by clicking on it and then “Remove Split”

Default selection

The more control points selected, The less indoor units can be connected to the LON interface 24 SNV / unit x 64 units = 1536 + 7 General SNVT‟s 1543 However, only 300 of them can be used due to LON bus restrictions (to guarantee data transmission)!  More SNVT‟s* = Less indoors

* SNV: Standard Network Variables = control points ** SNVT‟s: [snivits] Standard Network Variable Types

Default setting: 7 SNVT / indoor (300 – 7) / 7 = max 41 indoors on one F1/F2 circuit A standard refresh rate of 30 seconds is used.

64

9-11. Preferences screen In the advances tab of the preferences screen the default setting is that all indoor units receive a group address. Even if you would decide that indoor units work as master/slave on one remote controller, every indoor should still get its group address. If you would decide otherwise, Proportional Power Distribution (PPD) and possible error codes for non-addressed indoors cannot be allocated to the particular indoor unit. If you would deselect this item, the following indoor listing would be seen. If you select a single unit from that list, you can individually edit it (double click) to make the group address choice.

Edit indoor and allow to deselect the group address setting
